This citation summarizes a one-page announcement of technology available for utilization. Active fluidic dampers may be the best answer amoung possible alternatives for controlling subsynchronous whirl in turbopump shafts. A preliminary study indicates that a linear variable-bleed detector and a linear bistable amplifier are effective in supplying sizable controlled damping forces. A possible linear bistable damping system was developed using four detectors and four power amplifiers. ...FOR ADDITIONAL INFORMATION: Contact: The Patent Counsel, Marshall Space Flight Center, Alabama.
